STOPPER AND LIQUID-DROPPER FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 449,291, dated March 31, 1891.

Application filed November 1, 1890. Serial No.8'70,04'7. (No model.) Patented in France September 28, 1889, No. 202,282, andin England January 10, 1890, N0. 478.

T at whom it may concern.-

Be it known thatI, VIoroR CHARLES MON- ETTE,a citizen of the Republic of France, and a resident of Paris, France, have invented certain Improvements in Stoppers and Liquid- Droppers for Bottles, (for which I have been granted patents in France, No. 202,282, dated September 28, 1889, and in Great Britain, N0. 478, dated January 10, 1890,) of which the following is a specification.

My invention relates to devices for measuring or serving out liquids drop by drop or in small quantities; and the object is to pro vide a dropper capable of accurate regulation with the fingers and mounted in the stopper of the bottle, and to provide a stopper that cannot be removed from the bottle Without injury to either the bottle or stopper.

' The invention will be fully described here: inafter and its novel features carefully defined in the claims.

In the accompanying drawings, which serve to illustrate my invention Figure l is a horizontal axial section of a stopper provided with my improvements, and Figs. 2 and 3 are respectively transverse sections of the same in the planes indicated by the lines 2 2 and 3 3 in Fig. 1. Fig.4.isasection similar to Fig. 1, showing the stopper in place in the bottle; and Figs. 5 and 6 are re spectively transverse sections of the same, taken in the planes indicated by lines 5 5 and 6 6.

A is the body portion of the stopper,which will preferably be of metal, the plug a being partly covered by a sleeve or jacket c, of cork or the like, to form apacking. In the head ta of the stopper is a passage b, through which the liquid escapes from the bottle. The plug of the stopper, which fits into the neck Z of the bottle, is hollow, and arranged within it is a sliding hollow conical or other shaped wedge c, which has in it apertures or perforations (:1, one or more, to permit the liquid to pass on its way from the bottle to the liquidoutlet 1). In the walls of the plug are setlaterally-sliding pins or pieces e, of which there may be one or more. Four are shown in the drawings. The purpose of these pins will be hereinafter explained.

In the head of the stopper A is arranged the regulator f, which will be by preference a metal plate set in a recess in the head and pivoted thereto at g, so that it has a little lateral play, like a Wicket. This part f, WhichI term an obturator, has its projecting free end h roughened or serrated, so that the finger when applied to it for moving the obturator will not slip. This obturator crosses and cuts off the passage b, and at this point it has set in it a piece of cork i, in which is a hole j, that may be put into or out of register with the passage 1), thereby providing a means for regulating the size of the outlet for the liquid.

In Figs. 1 and 2 the obturator f is represented as set so that the passage b is wholly closed, and in Figs. 4 and 5 it is represented as set so that the hole j is coincident with the passage 1).

The bottle to which the stopper is to be applied has formed within its neck Z a groove or recess 3 which,when the stopper is inserted, stands opposite to the pins or pieces 6 in the stopper-plug, and after the insertion of the stopper a suitable rod 00 is inserted through the passage b and the wedge c pushed down thereby, as seen in Fig. 4., until the wedge shall have driven the pins e outward into the groove y. The rod to is now withdrawn, and the stopper cannot be removed from the bottle, owing to the engagement of said pins with said groove. The wedge 0 should be sufficiently elastic to cause it to press tightly against the walls of the hollow in the plug, and so retain its place firmly when driven down or inward.

The bottle having been filled previous to the insertion of the stopper, the obturator f may be pushed to the position seen in Fig. 2, and the bottle will be closed against leakage.

I am aware that it is not new, broadly, to provide a bottle-stopper with a passage through it for the liquid in the bottle and with a slide to close said passage, and this I do not claim. The object I have in View is to provide a stopper with means for controlling the flow of liquid therethrough, and also to provide means whereby said stopper may be irremovably secured in the bottle. The purpose of this is, in part, to prevent the empty bottle from being refilled and in part to compel the user to utilize the contracted passage in the stopper, thus directing attention to the dropper.

Having thus described my invention, I claim 1. As an improved article of manufacture, a stopper comprising a head having in it an outlet or passage 1) for the liquid, a hollow plug provided with a sliding piece or with pieces 6 set in apertures in its sides and projecting normally into the hollow of the plug, and an apertured Wedge 0, arranged within said hollow in the plug and adapted to drive said pieces outward when forced down, substantially as set forth.

2. As an improved article of manufacture, a stopper A, having a head with an outletpassage in it, and means, substantially as described, for controlling the flow of liquid therethrough, a hollow plug having sliding pieces 6 mounted in apertures in its Walls and projecting normally into the hollow of the plug, and an apertured wedge 0, arranged within the said hollow and adapted to drive said pieces outward when forced down, substantially as set forth.

In witness whereof I have hereunto signed my in the presence of two subscribing witnesses.

VICTOR CHARLES MONETTE.
